Abstract
A system for cleansing wounds with a fluid jet includes a pressure pump (900) for generating a fluid jet, a handpiece body (200) with a nozzle (204) for emerging the fluid jet, a fluid line (90) connecting the pressure pump (900) with the handpiece body (200), an adapter (700) holding a porous body (510), the adapter (700) being releasably connected to the handpiece body (200). The adapter (700) and the porous body (510) comprise a free inner space (770, 570) into which the fluid jet emerges when leaving the nozzle (204). The adapter (700) is at least partially transparent, thereby enabling a view into the inner space of the adapter and the porous body. The system according to the invention combines the advantages of cleansing by a fluid jet with the advantages of mechanical cleansing and, at the same time, provides effective protection against aerosols.
Core Innovation
A system for cleansing wounds with a fluid jet uses a handpiece body with a nozzle for emerging the fluid jet and a fluid line connected with the handpiece body. An adapter holding a porous body is releasably connected to the handpiece body, and the porous body has a lower surface shaped to be placed on a patient's skin around a wound to be cleaned.
The adapter and the porous body comprise a free inner space into which the fluid jet emerges when leaving the nozzle. The porous-body arrangement forms an on-skin protective sleeve or sleeve-like structure with a free inner space, and at least portions of the adapter are transparent, enabling a view into the inner space of the adapter and the porous body and thereby enabling a view of the wound to be cleaned.
The disclosed embodiments include different handpiece geometries, porous-body materials and shapes, optional suction channels, and adjustable jet emergence direction and spacing. The document describes combined fluid and mechanical cleansing effects and reducing aerosol spread while enabling visual monitoring through transparent portions of the adapter.
Claims Coverage
The partial claim set includes two independent claims. The independent claims center on a wound-cleansing fluid jet delivered through a handpiece nozzle into a free inner space defined by a releasably connected adapter holding a porous body placed on the patient’s skin around the wound, combined with adapter transparency to enable viewing of the wound.
Releasably connected porous adapter with free inner space jet emergence
A handpiece body with a nozzle for emerging the fluid jet; a fluid line connected with the handpiece body; an adapter holding a porous body, the adapter being releasably connected to the handpiece body; the porous body has a lower surface shaped to be placed on a patient's skin around a wound to be cleaned; and the adapter and the porous body comprise a free inner space into which the fluid jet emerges when leaving the nozzle.
Transparent adapter enabling viewing of the wound and inner space
The adapter is at least partially transparent, thereby enabling a view into the inner space of the adapter and the porous body and thereby enabling a view of the wound that is to be cleaned.
Wound-cleansing unit comprising adapter and porous body
A unit comprising an adapter and a porous body of a system for cleansing wounds with a fluid jet, where the system includes a handpiece body with a nozzle for emerging the fluid jet and a fluid line connected with the handpiece body, and where the adapter holding the porous body is releasably connected to the handpiece body; the porous body has a lower surface shaped to be placed on a patient's skin around a wound to be cleaned; and the adapter and the porous body comprise a free inner space into which the fluid jet emerges when leaving the nozzle.
Across the independent claims, the core claim coverage is the same: a wound-cleansing system where a releasably connected adapter holding a porous body defines a free inner space for jet emergence, with the porous body positioned on skin around the wound, and adapter transparency to enable viewing into that inner space and the wound.
Stated Advantages
Enables a view of the wound that is to be cleaned.
Enables a view into the inner space of the adapter and the porous body.
Reduces aerosol spread.
